The ever increasing popularity of web applications is a double-edged sword for many enterprises today. The business side loves that users can be productive from any location with any Internet-enabled device. However, the IT side is often left struggling with network issues and poor performance resulting from the growing complexity and volume of these browser-based apps.
SearchEnterpriseWAN's Jessica Scarpati explores exactly that in "Web application performance: Complex apps make problems for WAN pros." The sheer number of Web and collaboration apps, the fact that many are interconnected or are used as portal to others business applications, their intolerance to packet loss and the competition with the other apps result in timing out, slow performance and finally unusable services. This reduces adoption of Web applications, impacts the productivity and finally affects the image of the IT department.
What strikes here is the incredibly diverse nature of the problems – take just the network, for example: from the intrinsic quality of the transport (please, don't use a network that discards every third packet…), scarce bandwidth in costly locations, competition among users, new cloud-based applications, bandwidth usage explosion, uncertainty about Internet performance, etc.
Applying ad-hoc medicine on such various – and moving – situations will likely lead to disappointing results, costly deployments and fuzzy operations, giving the impression that the IT is pottering about. At Ipanema we believe that this situation can be prevented if we start from the beginning: 1) defining the performance objectives, 2) understanding what's going on, and 3) implementing dynamically the necessary technics to each application connections to guarantee business apps performance and maximize the value of the network to the business.
Believe it or not, this is truly simple: the enterprise just needs to define a few APOs (Application Performance Objectives) for their business applications, and then AQS (Application Quality Score) will automatically show where the performance stands and the autonomic system will automatically control and optimize each user connection to match – or exceed – the defined performance.
Automatic alignment to SLAs across the enterprise WAN alleviates IT — and business — issues of poor performance, usability and overall traffic flows. Building a network and application performance strategy around your users will allow your enterprise to support the complex web applications, user-centric collaboration tools and cloud services that are essential to today's business environment.
